ユニオンを使用してロールアップされた値を表示する方法

Question

私はDB2構文を使用していて、UNIONを使用してロールアップされた値を表示する追加の行を作成したいと考えています。

これを行うのではなく、2番目の共用体からのデータが表示されるのに対し、ユニオンの最初の部分は単に列の名前を付けるだけです。ここで

は、第一の部分

SELECT 'DRIVER ID' AS DRIVER_ID, 'NAME' AS NAME, 'PUNIT' AS PUNIT, 'PHONE' AS PHONE, 1767 AS TERMINAL_NUMBER, 'DRIVER TYPE' AS DRIVER_TYPE, 
COALESCE((SELECT ROUND(DEC(SUM(CASE WHEN UPDATED_BY IN ('VISTAR','TM4WIN') THEN 1.00 ELSE 0.00 END))/COUNT(UPDATED_BY),2) FROM ODRSTAT, TLORDER L, DRIVER D WHERE DETAIL_LINE_ID = ORDER_ID AND STATUS_CODE IN ('ARRV@SHIP', 'ARRV@CONS', 'DEPT@SHIP', 'DEPT@CONS')

である私はあなたのコードを見ていませんでした...フォーマットの欠如を考えると、それは従うことは簡単ではありません。

しかし、以前はUNIONを使用して値をロールアップしていましたが、詳細と合計を区別するための余分な列が追加されました。これらの追加の列もORDER BYに最初の列として使用されている

例：

select      
    digits(HCUSNR) as Cust_Num, 
    CCUSNM, 
    char(HINVNR), 
    hinamt, 
-- Control fields     
    ' ' concat digits(HCMPCL),  
    case        
    when HTRCDE in ('A', 'E', 'R') 
     then ' LVL3'    
    else ' LVL1'     
    end,        
    HCUSNR, DDVDSC, HDIVSN   
UNION ALL 

select  
    ' ', 
    'Daily Invoice Total', 
    ' ', 
    sum(hinamt), 
-- Control Fields          
    ' ' concat digits(HCMPCL), ' LVL2', 0, ' ', HDIVSN 
group by    
    HDIVSN, HCMPCL 
--Following order by applies to entire results set 
order by 5,6,7,8,9 

しかし、上記は近くに20年前に書かれた...

私は今日それを行うために必要な場合には、 IBMがDBに追加したグループ化セット、ロールアップ、およびキューブの機能を使用したいと思います。

DB2のどのプラットフォームおよびバージョンを使用していますか？グループ化セット、ロールアップおよび/またはキューブはオプションですか？
